THEODORE A. KUNDSON, OF WANNASKA, MINNESOTA.

PORTABLE S pTU MP-PU LLER.

SPECIFICATION forming part of Letters Patent No. 728,248, dated May 19,1903.

I Application filed March 7,1902. serial No. 97,183. (No model.)

dent of Wannaska, county'of Roseau, and

State of Minnesota,have invented certain new and useful ImprovementsinPortable Stump- Pullers, of which the following is a specification,reference'being had to the accompany:

similar letters of referenc'edndicate corresponding parts. o

This invention relates to portable stumppullers; and the object-thereofis to provide an apparatus of this character which is effective inoperation, simple in construction, and durable, and which can bereadilymoved from place to place.

The invention will be hereinafter fully described, and specifically setforth in the annexed claims.-

In the accompanying drawings, forming part of this specificationfFigure'I is'a plan view of my improved apparatus, and Fig; 2a

side elevation thereof.

In the practice of'myinvention I provide,

primarily, a platform or bed A, which is composed of strongtimberembodying the longitudinal beams a and cross-bracesa. Coveringthis framework is a flooring-A, and the whole is mounted upon suitablerunning-gear,v

as B B, whereby the structure can readily be moved from place to place.Upon the forward end of the platform A is mounted a motor of any adaptedcharacter, preferably a gasolene-engine, as O. This engine drives apulley D, which is mounted on a shaft E, which is journaled through abox E, secured to the platform A. Thispulley is connected to thefly-wheel o. of the engine 0 by means of a belt F. To the outer end ofthe shaft E is connected afpulley Ggand this pulley is in connectionwith a similar pulley H by means of the belt I. The said pulley H ismounted on the end of a shaft J, which is journaled through boxes K,mounted upon extensions A of the platform A. This'shaft J is alsoprovided with a securely-connected reel L, which carries a coil of wirerope M for connection with the stump to be pulled.

I do not confine myself to the use of belts and pulleys as the means forconnecting and operating the parts, as it is obvious that I iPatent, is-

I mayemploy sprocket-wheels andhchains, if

desired. A-strong chain may-also be substitutedrfor the rope M. A rope.or chain, as N, is also attached ;t0 t'he front oftheapparatus'by'meansofth'eieyesn. This rope or chain may be of anydesired length, and it is employed to fasten the apparatus-toanysuitable stationaryobject while it is in use.

' lnth'ebperatidn'and use of the invention when it isdesire'dtO extracta'stump, heavy stone, or other object the apparatus is first fastenedor, tied to a tree by means of the rope N. The rope or chain M is thenpartly unwound from the reel L and connected at its free end to thestump or other object to be extracted, after which the motor is startedand rotary motion imparted to the reel L,

which exerts a winding and'pulling motion on the rope M and extracts thestump by means of-a'gradual pull thereon.

Having thus described'my invention, what 'I'claim as new, and desire tosecure by Letters 1.1 In a stump e2 ztra ctor, the combination withaplatform, comprising. a floor, secured upon longitudinal beams fandcross braces,

and wheels whereon saidplatform is mounted, of a motor mounted o'nsaidplatform near one end thereof, with its driving-shaft parallel-to theplane-thereof,f"'a shaft journaled in bearings upon the other end ofsaid platform parallel to the plane of said platform, an intermediateshaft journaled on said platform parallel to the plane thereof betweensaid motor and said end shaft, pulleys on said motor and said shafts,wrapping connections conveying motion from said motor to saidintermediate shaft, and from said intermediate shaft to said end shaft,and means for'connecting said end shaftwith a stump, for extracting thesame. p;

2. In a stump-extractor, the combination with a platform,comprisinga-fi0orfsecured upon longitudinal beams and cross-braces, andwheels Whereon said platform is mounted, of a motor mounted on saidplatform near one end thereof, with its, driving-shaft parallel to theplane thereof, an end shaft journaled on the other end of said platform,parallel to the plane thereof, an intermediate shaft journaled upon saidplatform parallel to the plane thereof, between said motorand said endshaft, pulleys on said motor and said shafts, wrapping connectionsconveying motion from said motor to said intermediate shaft, and fromsaid intermediate shaft to said end shaft, a reel upon said end shaft, aflexible connection to attach said reel to a stump for extracting thesame.

3. In a stump-extractor, the combination with a platform comprising afloor and longitudinal beams and cross-braces whereon said floor issecured, and wheels whereon said platform is mounted, of a motor mountedon said platform near one end thereof, with its driving-shaft parallelto the plane thereof, eyes secured to the same end of said platform, acable passing through said eyes to secure said platform in position, anend shaft journaled on the other end of said platform, parallel to theplane thereof, an intermediate cable or chain to connect said reel witha stump, and arranged to wind upon said reel, and extract such stump.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 25th day of April, 1901.

THEODORE A. KUNDSON.
